11 CZMIL (Coastal Zone Mapping and Imaging Lidar) Combining topographical and bathymetric LIDAR enables survey to be taken of coastline, giving the maximum overlap between the land / sea interface Surveying the shallow areas around the cost would be difficult and time consuming with standard multibeam echosounder survey. With airborne LIDAR large areas can be flown in a short period of time, obtaining snapshots of coast at specific time intervals.

12 CZMIL hardware BS Laser Sensor Head Chassis CASI 1500 Spectrometer Optech T-4800 Metric Camera (16 Mpixel) IMU Optech CZMIL is an innovative airborne coastal zone mapping system that produces simultaneous high resolution 3D data and imagery of the beach and shallow water seaflor. Radiation at 532 nm is well suited for transmission through the water while 1064 nm radiation is strongly absorbed.

13 CZMIL laser Pulse energy: nm nm Pulse duration: 2 ns Peak Power: > 1 MW Repetition rate: 10 khz Two collinear laser beams, nm and nm are provided at laser output. The beam at 532 nm detects the seafloor while the beam at 1064 detects the sea surface.

14 AMPLE (Aerosol Multi-wavelength Polarization Lidar Experiment) A new lidar system for the characterization of highly polluted urban areas (co-operation between CNISM Beijing Research Institute of Telemetry) and volcanic emission monitoring (a co-operation between CNISM and INGV/INAF)

15 AMPLE (Aerosol Multi-wavelength Polarization Lidar Experiment) Designed to perform 3D measurements by scanning the atmosphere along the azimuth and the zenith angles with a scanning of 10 s-1 and a precision better than 1'. Laser transmitter Two units of the AMPLE have been realized for the Beijing Research Institute for Telemetry and the National Geophysics and Volcanology (Catania, Italy).

17 Conclusions Wedge family DPSS lasers and pwedge platform particularly suited for LIDAR applications for short pulse durations (< 500 ps in Wedge XF), pulse energies (up to 4 mj in Wedge XB lasers), compactness and ease of integration Even shorter pulse durations for higher spatial resolutions are under investigation (Wedge and Pico series) Laser sources initially born for micromaching applications, rugged and thought for uninterrupted 24-hours a day operation have been adapted to meet requirements for aerospace applications, in terms of compactness, weight and higher level of integration Compactness and integration produced positive feedback also in the industrial market applications Nowadays the trend is to offer air-cooled single-box solutions, thus integrating all optics and driving electronics together
